oxronn EYEGLASSES.

Application filed June 14, 1926. Serial No. 115,810.

This invention relates to the so-called Oxford type ofeye-glasses, i.e., eye-glasses in which each lens frame is attached by a spring-pivotconnection to oneend of an approximately straight plate-spring orelastic bridge connecting the lens frames and the instrument istherefore adapted to be folded when not in use so that the lens framesare opposed to andsubstantially register with each other, being thenlocked in this position by a spring-catch on a handle projecting fromone of the frames engaging a lug or notch on the other.- Such eyeglassesare of course provided also wlth nose-guards or nose-clips, and it ISnecessary that in the folding and unfolding these parts should pass eachother without preventing the completion of the movement and with aslittle interference as possible. Usually each nose-clip consists of apad formed with a projecting supporting arm which is attached to thecorresponding lens frame, and in the construction heretofore known (seethe Hutten et al. Patent #1,016,153, for exarm was not only short but itjoined the pad at the forward side thereof, which construction possessedthe fault that it very much limited the possibility by bending the armfor fitting the mstrument to suit each particular wearer and in manycases required the entire removal of the arm from the lens frame inorder to either shorten or lengthen it.

My object by the present invention is to rovide a pair of eye-glasses ofthe type 1ndicated with nose-clips which, whlle per mitting the foldingand unfolding of the instrument without undue interference of thenose-clips with each other, shall be so constructed that adjustmentthereof for every possible condition may be accomplish ed simply byreadily effected bending opera tions.

In thedrawing,

Fig. 1 is a fragmentary rear View of a pair of Oxford eye-glassesembodying my invention, the same showing one lens frame and itsnose-clip;

Fig. 2 is an inside elevation of what is seen in Fig. 1;

Fig. 3 is a fragmentary plan of the lens frame and nose-clip shown inFig. 1;

Fig. 4 is a rear elevation of the improved eye-glasses; and

Fig. 5 shows the blank from which a nose-clip according to thisinvention is made;

Each lens frame 1, plate-spring or elastic bridge 2 having spring-pivotconnections 3 with the lens frames, the handle 4 projecting from onelens frame, and the spring catcl'r 5' on said handle adapted to engage 7and its forward edge formed with a salient angle 7 but this particularform of the pad is not especially material. Projecting from the pad atits rearward portion and centrally of its convex side is an arm or post8 which is bent off from and forwardly with respect to the pad. This armis attached permanently to the corresponding lens frame, as by brazingit thereto and at about the position shown in the drawing.

In order to form the nose-clip the pad and arm may be stamped from asingle piece of sheet metal, at which time said pad and arm would lie inthe same plane (Fig. 5). After the part is stamped out the arm will thenbe bent off into that relation to the pad which has above beenindicated. By following this method the pad and arm will be integral,thus reducing the possibility of breakage at their point of juncture ifany bending is to be done in that vicinity in fitting the glasses to thewearer. I note further that the arm 8 affords at 8 a bend presenting arearwardly convex curved surface which is rearward of the pad and ineffect forms a camming surface for a purpose to appear.

Since the arm or post 8 projects from the rear portion of the padinstead of from its forward portion it is desirably longer than the armof the known construction, and in View of this and its relation to thepad (flanking the same) there is permitted much wider range ofadjustment of the pad by bending the arm, and moreover the arm willundergo considerable bending without breakage or unduly straining an] ofthe parts. Thus the two nose-clips can be adjusted toward or from eachother, forward and back, up and down or to different angularity onvarious axes to a practically unlimited variety of positions so as tosuit the facial conditions and also effect a proper centering of thelenses and the correct pupillary distance thereof from the wearers eyes.Such adjustments are all possible simply by bending each or both of thenose-clips, and in no case is removal of either arm from the lens framenecessary.

Atthe same time the folding and unfoldin operations are possible withoutundue interference of the nose-clips with each other, nor can theyaccidentally be caught on each other at that step in the folding orunfolding movement when they are in a partly folded condition. This isprincipally because each arm at S is developed as a bump, projectingrearward of the pads, which if the front edge of one nose-clip wouldotherwise catch on the rear edge of the other, serves to cam or fend itoff and so prevent an interlock.

Having thus fully described my invention what I claim and desire tosecure by Letters Patent is:

Folding eye-glasses of the class specified including a pair of lensframes, an elastic bridge having a spring-pivot connection with eachframe, and nose-clips for the re spcctive frames each consisting of apad arranged to lie in a front-to-rear plane and an arm projectingrearwardly from the rear portion of the pad and bent forwardly and beingrigidly secured to the corresponding lens frame. said arm adjacent thebend being formed with a rearu 'ardly convex hump, said hump beingadapted to cam off the forward portion of the opposite nose pad oncontact of said nose clips in passing each other when the eye glassesare folded or unfolded.

In testimony whereof I aflix my signature.

HARRY HIGHAM.
